Alignment method:
Initial Set-up:
1>. Select source as “PC”.
2>. Set Contrast = 50 (CMO) and Brightness=50 (CMO) , at normal menu mode.
3>. Apply “5 white block”(pattern-1) pattern by VGA pattern generator.
4>. Enter factory mode menu: press MENU + Numeric keys “062596” + MENU key (FAC mode menu). Then select “Factory” item.
Alignment:
1>. At FAC mode menu, select AUTO_COLOR item. Then press “OK” key to adjust ADC_GAIN_R, ADC_GAIN_G, ADC_GAIN_B and ADC_OFFSET_R,
ADC_OFFSET_G, ADC_OFFSET_B. Then store those values to NVM.
2>. Apply Flat80 pattern (80% white pattern).
3>. Set color temperature to “NORMAL”.

Alignment method:
Initial Set-up:
1>. Select source as “YPbPr”.
2>. Set Picture mode as “User” and to be Contrast =50 (CMO), Brightness=50 (CMO) , at normal menu mode.
3>. Apply “TVBar100” pattern with color bar pattern by signal generator.
4>. Enter factory mode menu: press MENU + Numeric keys “062596” + MENU key (FAC mode menu).Then select “Factory” item.
Alignment:
1>. At FAC mode menu, select AUTO_COLOR item. Then press “OK” key to adjust ADC_GAIN_R, ADC_GAIN_G, ADC_GAIN_B and ADC_OFFSET_R,
ADC_OFFSET_G, ADC_OFFSET_B. Then store those values to NVM.
2>. Check the 16 grayscale pattern should be distinguished and color bar is correct
3>. Reset AV setting, picture mode shall be recalled to be “Vivid” and Contrast=48, Brightness=58
3>. Reset AV setting, picture mode shall be recalled to be “Vivid” and Contrast=48, Brightness=58
3) HDMI HDCP Key Download
1>. HDCP Key Encryption
The handling of HDCP keys must be done in the most secure way. The HDCP keys purchased / delivered from Digital Content Protection, LLC are first
encrypted by MTK encryption software. Then the encrypted keys are stored in secure room or secure PC in production line.
encrypted by MTK encryption software. Then the encrypted keys are stored in secure room or secure PC in production line.
2>. HDCP Key Downloading to Set
In production line PC, execute HDCP key programming software to load encrypted key data from secure room or secure PC to specific positions of set’s

NVM via UART interface of MT533x chip.
3>. Test HDCP Key
Use QuantumData 802BT or equivalent instrument with HDCP test pattern to verify HDCP key loaded in the set. The “PASS” information will be shown in
the lower center block of the screen when HDCP key is correctly loaded.
Use DVD player Pioneer DVD player or equivalent DVD player with HDMI output to verify HDCP key loaded in the set. The video should be smoothly
displayed when HDCP key is correctly loaded.
